SPP is seeking FERC approval for a revised Tariff that the RTO says will more accurately screen generators for market power abuses.

This week, we welcome David Cruthirds to the RTO Insider team with his first of hopefully many columns, providing insight into MISO and Southern Co.

Demand response and advanced meters are continuing to grow but progress is uneven, with some regions showing reductions, according to a new report by FERC.

Depressed coal stockpiles have led to increases in MISO’s off-peak power prices and the cost impacts could increase with a repeat of last winter’s severe cold, officials said last week.

The Federal Energy Regulatory Commission has consolidated four years of Entergy Corp.’s disputed annual cost allocation cases for hearing and settlement.

RTOs joined a chorus of critics last week in warning that the EPA's proposed Clean Power Plan threatens grid reliability, saying the agency should provide more time for compliance.
